In another of the ongoing rounds between diesel versus hybrid we bring you two heavyweight contenders, the Chevy Tahoe hybrid, which we had in the AutoblogGreen garage, versus the Mercedes-Benz GL320 CDI. Actually, it's brought to you by the good folks at Edmunds who took it upon themselves to give these two a through shakedown. As I'm sure you've already noticed, these are two humongous SUVs that we don't consider especially green but for those folks who need to tow large trailered objects or haul large families they are relatively more green than their forebears.
The competition between these two was pretty tight for a while. Pricewise, the Mercedes was only $480 more than the Chevy for the base model though the Chevy became a pretty good bargain once the options came into play. Both of the beasts excelled at acceleration (8.5 second, 0-60) with the Tahoe ahead by the slimmest of whiskers as long as they traveled in a straight line. With the cones set up, the Mercedes superior agility really shone, whipping through the course at 60 mph while the Tahoe had more waddle than a flock of ducks on the hoof. Also, in the all important fuel economy category, the diesel pulled decisively ahead, at one point returning 26 mpg during a stretch of highway driving where the Tahoe could "only" eke out a 21.9 figure over that same stretch. Advantage diesel. To watch these two duke it out auto à auto, hit the jump.
